Inbee Park set many golfing goals. Etching her name alongside Babe Zaharias was never one of them.

Yet now they're the only two players to win the first three majors of the year. Park became the first to accomplish the feat in the modern era Sunday with her second U.S. Women's Open title.

"Trying to put my name next to hers means just so much," Park said. "It's somewhere I've never dreamed of. But all of a sudden, I'm there."

The world's top-ranked player finished at 8-under 280 to win by four shots in Southampton, N.Y. Her closing 2-over 74 was more than enough, with Sebonack's trying conditions keeping any rivals from making a run.

I.K. Kim also shot 74 for her second runner-up finish at a major. So Yeon Ryu (72) was third at 1 under. South Koreans took the top three spots and have won the last five majors.

Zaharias won the year's first three majors in 1950 -- back when there were only three. Now there are five, so Grand Slam might not quite be the right term if Park wins all of them. Ahead by four shots at the start of the day, Park birdied Nos. 9 and 10 to extend her lead. She has won six times already this year, including three straight events.

Park, who won $585,000 on Sunday, added to another historic U.S. Women's Open victory in 2008, when she became its youngest champion at 19.

"It was a great championship then, but now I appreciate it more," she said.

Soon-to-be Oklahoma State player Casie Cathrea of Livermore shot 70 -- tying for the best round of the day -- and was low amateur at 9 over.

"I was just trying to stay in my own bubble (and) not get ahead of myself," Cathrea said.

San Jose's Christina Kim (74) finished at 10 over.

Jessica Korda, who fired caddie Jason Gilroyed midway through the third round, tied for seventh at 2 over. She closed with a 73 with her boyfriend, Johnny DelPrete, on the bag again.

PGA Tour: Bill Haas won the AT&T National thanks to birdies at Nos. 8-10 and one fortunate hop. It led to a 5-under 66 at Congressional and a three-shot win over Roberto Castro in Bethesda, Md.

As many as six players had a share of the lead at some point until Haas made a 10-foot birdie putt on No. 8. Haas, who earned $1,170,000, has won at least one tour event in each of the last four years. He finished at 12-under 272.

Castro, part of a four-way tie for the lead at the start of the day, had a 69. The other leaders fell away. Andres Romero had a double bogey on No. 4 and shot 75. James Driscoll didn't make a birdie in a 74.

Haas picked up an unlikely birdie on No. 14 when his 9-iron was drifting toward a mound covered with shaggy rough to the right of the green. The ball hopped off the mound to within 10 feet of the pin.

Champions Tour: Kenny Perry won the Senior Players for his first major title, overtaking Fred Couples with a 6-under 64 in Pittsburgh. Perry finished at 19-under 261 at Fox Chapel, two shots ahead of Couples (68) and Duffy Waldorf (64). Perry, who won $405,000, hit close to the pin on Nos. 16 and 17 for tap-in birdies. San Mateo's Michael Allen (65) and John Huston (68) shared fourth at 12 under.

European Tour: Paul Casey made a 50-foot eagle putt on the 18th hole and won the Irish Open by three shots in Maynooth. He had a 5-under 67 to finish at 14-under 274. Robert Rock (71) and Joost Luiten (74) shared second.
